Peterbilt 367 Air Springs

Peterbilt 367 Air springs

Air springs for the Peterbilt 367 start at low prices, and AutoBuffy stocks multiple options from top OE-quality brands. An air spring replaces a conventional coil spring by using a pressurized rubber bladder to support the vehicle's weight and absorb road impacts. When one fails, the corner sags, the ride turns harsh, and the compressor runs constantly trying to compensate — causing a chain of expensive secondary damage.

Signs your Peterbilt 367 needs new air springs

  • One corner of the vehicle sits noticeably lower than the others, especially after sitting overnight
  • The air compressor runs for unusually long cycles or activates every few minutes while parked
  • A hissing or rushing-air sound is audible near a wheel well when the suspension moves or the compressor runs
  • The ride feels harsh, bouncy, or bottoms out over bumps that were never a problem before
  • A 'Suspension Fault,' 'Air Suspension Low,' or warning light appears on the instrument cluster
  • Uneven tire wear on one side or corner of the vehicle, indicating chronic low ride height at that corner

Which air spring should you buy for your Peterbilt 367?

The main decision is whether to replace the failed air spring with an OE-style air bladder, a complete strut-and-spring assembly, or to convert the system to passive coil springs entirely. Your budget, how long you plan to keep the vehicle, and whether other air suspension components are already worn will determine the best path. Position — front or rear — also matters, as the designs and load ratings differ.

OE-style replacement air spring (bladder only)
Best for
Owners who want to preserve the factory air suspension and whose compressor and valves are still healthy
What you get
A direct-fit rubber or sleeve-style bladder that restores original ride height and comfort with minimal additional parts
Complete air strut assembly (spring + strut + mount)
Best for
Front positions or any corner where the strut, mount, or bump stop is also worn
What you get
A pre-assembled unit that eliminates multiple failure points at once and often requires no spring compressor to install
Rear air spring with internal bump stop
Best for
Rear positions on trucks, SUVs, and luxury vehicles carrying variable loads
What you get
A self-contained bladder with a built-in jounce bumper that prevents metal-to-metal contact under full compression
Coil spring conversion kit
Best for
High-mileage vehicles where the compressor and other air suspension components are also failing, or owners who want to eliminate future air system costs
What you get
Passive steel coil springs and passive struts or shocks that permanently replace the air suspension — no compressor required, modest ride quality trade-off

Replacing air springs on a Peterbilt 367

Moderate⏱ 1.5–3 hours per axleFloor jack and jack stands rated for vehicle weightBasic socket and ratchet set (metric and standard)Air line disconnect tool or small pick for fitting clipsTorque wrenchScan tool capable of suspension reset (for electronically controlled systems)

The vehicle must be raised and supported securely, and on electronically controlled systems the air suspension should be vented or set to service mode before disconnecting any air lines to avoid pressurized line injuries. The air spring bladder or complete strut assembly is unbolted from its upper mount and lower perch, the air line fitting is disconnected, and the new unit is installed in reverse order. After installation, a suspension height calibration with a compatible scan tool is recommended before returning the vehicle to normal operation.

Frequently asked questions

How much does it cost to replace air springs on a Peterbilt 367?
Parts alone start at low prices for a single air spring on the Peterbilt 367. A complete air strut assembly or a set of four springs will cost more. Professional installation adds labor on top of parts, so many owners replace air springs in pairs or axle sets to reduce repeat labor costs down the road.
Can I drive my Peterbilt 367 with a failed air spring?
Driving on a failed air spring is not recommended beyond moving the vehicle a short distance. The affected corner drops to its lowest position, overloading the bump stop and potentially contacting the wheel well or damaging brake lines and CV axles. Extended driving accelerates wear on adjacent suspension and steering components.
How long do air springs last on a Peterbilt 367?
Air spring lifespan varies widely based on climate, road conditions, and load use. In general, expect a range of roughly 80,000 to 150,000 miles or ten or more years, whichever comes first. Cold climates accelerate rubber cracking, and vehicles that regularly carry heavy loads or tow wear air springs faster than lightly used vehicles.
Should I replace air springs in pairs on my Peterbilt 367?
Replacing both air springs on the same axle at the same time is strongly recommended. If one bladder has failed, the other on the same axle has typically experienced identical heat cycles, load cycles, and age. A mismatched pair creates uneven ride height, unpredictable handling, and means you will likely be back under the vehicle soon for the second side.
Will replacing the air spring fix my Peterbilt 367's compressor running constantly?
It depends on the leak's location. If the air spring bladder itself is cracked or the fitting is leaking, a new air spring will stop the compressor from overworking. If the leak is in an air line, solenoid valve, or the compressor's check valve, those components also need attention — an air spring replacement alone will not solve it.
Do I need to recalibrate or reset the suspension after replacing an air spring on my Peterbilt 367?
Many vehicles with electronic air suspension require a ride-height calibration or a module reset after an air spring replacement so the system learns the new spring's characteristics and sets correct target heights. This is typically done with a scan tool. Skipping this step can leave warning lights on or cause the compressor to run abnormal cycles.
